    The yellow ones were 1/4" thick. I attach them to the monitors, then grind them down on a belt sander. The Kirinite I buy in 1/8" thick sheets, and cut it down into blanks on a bandsaw.

    You mean like these?? The three that are not yellow are Kirinite. The yellow one, I bought from eBay. Do a search for knife scales, you'll find all kinds of cool swirled acrylic stuff. I've tried making my own, so far with no success.

    That looks like a doming resin, probably with dye in it, on top of a brushed metal foil.

    If your ink is an opaque, it will either not work, or take a long long time to form a shell. I have a LED box with eight LED bars in it. It's WAY too strong. I can form shells in 12 seconds with clear resin. Using black, it's 20 min, and black resin is still translucent, barely. You...

    Right from the link you posted. Yes, it's a BA

    A single cap forms a 6dB/octave HPF. As far as how/why it works, google is your friend.

    Two ways. One is experimentation with just a single cap on the ED and a combination of a resistor(really doesn't act as a LP filter though) and dampers on the CI. The other, which is slightly more complicated, involves building an RC filter for each pass. The good news is that the...

    Never mind. Brain fart. You've got it right.

    You've got the RC filter on the Sonion 3300 wired as an LPF. Swap the components around.

    Especially since they are probably buying in 100,000 piece lots.

    The GV is a HODVTEC/TWFK. The GK is the CI/TWFK

    Fotosil is not perfectly clear either. Apparently Klarsil is. I have a Dosper, only because I got it for ridiculously cheap. Having used the 2L kit of Fotosil, I'm not sure if I'd bother with it again. It's not that much better than hydrocolloid, and it's pretty expensive. I figure about...

    Agreed. Someone doesn't grasp the concept of IN EAR.

    Unless you are using the same TWFK variant that they used two of, the cap values wouldn't necessarily be the same. If I were going to design a monitor using two TWFK, I would look for cap values with the ones I was planning to use, and start there.

    Yes, you've said that before. Have you had one, removed the cap, and measured it? If not, then your opinion is just that.

    Can't measure the cap without removing it. Not going to risk destroying a perfectly good driver.

    Yes!! As Wardy alerted me in a pm, Pro3dure's GR-1 is for printers in the 385nm wavelength, but they also have GR-10, which is designed for 405nm. I guess they figured out that if they could offer a biocompatible resin that those of us with budget machines could use, they'd clean up. I'll...

    So, with a few of us getting into 3D printing, how long before one of us bites the bullet and gets a 5 axis CNC so we can carve shells from other stuff, like Jerry Harvey??

    I don't know if they ship worldwide. I have a commercial account with them.

    While we work on print details, post processing, etc, just the anycubic clear. Once it seems we're close to being able to switch over, I have my eye on a few. Pro3dure GR-1, Surehold has one that isn't too expensive. Some of these are actually cheaper than their pouring resin counterparts.

    So, I ordered ten. I might be convinced to desolder a cap and measure it. That's IF these have 30017 on the side.

    It will be interesting to see what it says on the actual drivers. Very well could be just a 30017 with a cap and wires, but the graph looks markedly better than the one for the 30017, which is wired using a 0.82uF cap for that measurement.

    So, game changer new TWFK seems to be out. Prewired, with cap, and a much better response than the 30017. No affiliation. I do have some coming in for evaluation.

    I'm saving that one for the marketing blurb on my color free shells. "light passes clearky thru them"…
